This invention has for its object the provision of a window screen which will be autol matically drawn across the window opening as the window sash is raised and will be stored in a compact form as the sash is lowered. Another object of the invention is to provlde novel connections between the screen and the window sash whereby the screen will follow the movements of the sash and the opening below the sash will 'always be covered to prevent the entrance of insects. Another` object of the invention is to provide means whereby l the screen and the connections between the same and the sash will be eiectually protected from the weather. The invention is illustrated in the accompanying drawing and consists in novel features which will be hereinafter first fully l. described and then more particularly defined in the appended claims:

In the drawin Figure 1 is a liori'zontal section of a window equipped with lthe present invention,

Figure 2 is a vertical section of the same, Figure 3 is an enlarged detail elevation of a tension device which is employed,

Figure 4 is a section on the line 6-6 of Figure 3,

Figure 5 is a detail elevation of the roller upon which the screen is wound,

, Figure 6 is an enlarged detail section on the line 6-6 of Figure 5,

Figure 7 is an enlarged section showing the manner of connecting the screen to the sash.

The window frame 1 may be of the usual or any approved construction and has mounted therein an upper sash 2 and a lower sash 3 which are hung for vertical travel in the usual manner. In carrying out the present invention, a box 4 is secured upon the sill 5 of the window at or near theouter edge thereof and this box is composed of two sheet metal plates of arcuate cross section as shown in Fig. 2 and adapted tooverlap at their inner ends, as indicated in Fig. 1, the overlapping section being provided with a longitudinal slot 6 through which a fastening screw 7 is inserted to engage in the' over- 50 lapped section and thereby secure them in a.

set position. This construction permits the box to be easily adjusted to Windows of different widths. At the sides of the window frame similar boxes 8 are provided, these side boxes being secured to the side members of the window frame and having outer webs or rtions arranged in diverging relation to t e members lsecured to the window frame and having their lower extremities united. with the ends of the box 4 as shown at 9.

, The upper ends of the boxes 8 are closed and disposed to abut lthe upper sash 2 as showniat 10. Extending axially'within the box 4 is a roller 11 which is of tubular formation as shown most clearly in Fig. 6 and this4 65 tube consists of two members having their meeting ends adjustably or telescopically p .fitted one within the other as shown at 12 in Fig. 5. Longitudinal slots 18 are formed in the overlapping ends of the tube sections and .70 a fastening bolt 14 is fitted through the registerin slots so as to secure the sections of the tube 1n the position to which they may be adjusted. This construction facilitates the application of the roller to windows of different widths. As shown most clearly in Figs. 5 and 6, the tubular roller is formed with a longitudinal slot` 15 extending from end to end thereof. The screen 16 consists of a suitable length of wire nettin cloth or like material and one end thereo is iitted through the slot 15 of the roller and then crimped around one wall of the slot as shown at 17, a U-shaped binding strip or clip 18 bein then fitted over the crimped portion of t e screen and fastening screws 19 ,inserted therethrough whereby the end of the scree'n will be firmly secured to the roller. The screen is, of course, wound upon or unwound from the roller as the window sash is lowered vor raised and the opposite end edge of the screen is attached to the sash so that it will be controlled by the movements of the sash. To secure the screen to the sash there is provided a clamping bracket y20 95 which is secured to the lower rail of the sash on the outer side of, the same, as shown in Fig. 7, and this clamping bracket is substan- -tially Ushaped in cross section and has one 00 side,web secured to the sash and its parallel z l l 1,893,651

side web disposed vertically at the outer side the boxes 4 and 8 are also of sheet metal. of the sash. A clamping strip 2l is engaged The plates 30 are held between the angle of over the outer vertically extending side or the oxes 8 and the edges of the boxes b be- 'is folded or doubled upon itself to provide from the side edges of the respective boxes, 70

itself and engaged 'in the outer U-shaped and its upper end secured to the side of .the 75 upon the crimp or band of the screen and consequently yieldably holds the plate at upon the inner `band or crimp of the clampthe upper limit ofits movement. Should the ing strip so that the screen will be firmly cables 25 contract, the plates may move downheld in the clamping strip and the clamping wardly so as to accommodate the contraction strip likewise held firmly upon the bracket and avoid breaking of the cables. When the bent downwardly as shown at 23 whereby the close and draw the plates 30 upwardly go that 85 plate will constitute a cover to protect the the cables will be maintained in the desired other elements of the weather. rom the foregoing description taken in pon the ends of the roller 1l are secured connection with the accompanying drawin grooved pulleys 24 to which are secured the it will be seen that I have provided an exceed- 90 lower ends of the cables 25 which will wind ingly simple and compact mechanism whereupon and unwind from said pulleys in the by a screen may be attached to and operated operation of the screen. These pulleys are by a window sash and the working parts will provided ulpon their outer sides with trune eiiectually protected from the action of mons 26 w ereby lthey may be journaled in the weather. The screen is located on the 95 grooves in which the sash travels while ad 'a-ll window sash free to raised or lowered eas- 100' guide pulleys 28 are provided. The cables 25 The screen may be easily and quickly secured are passed at the rear of the pulleys 27 and in place without special tools or the use of then up to the front of the pulleys 28 and over skilled labor and the sash may be. raised to the atter end then down at the rear of the any desired height and the window opening same to be attached to the lower rail of the will always be covered by the screen. By besash, as shown at 29. s t e sash moves ing connected directly to the sash, the screen ownwardly,'the cables will be unwound from aids in balancing the sash so that it willrecables will cause rotation of said pulleys and 1Having thus described the invention, 110 l upon the roller.
